Cladistic reconstruction of diprotodontian interrelationships. Relationships and divergence estimates for extant lineages follow Duchêne et al.⁶. Those of extinct lineages follow Beck et al.⁵, Travouillon et al.¹⁰², and Crichton et al.^38,39. The divergence estimates for extinct vombatiforms and phalangeroids are speculatory.
